fix(ci): fix sidebar tests + add registry publish + prod compose

- sidebar.test: expand category before asserting on module names
  (categories are collapsed by default since UI-Umbau)
- ci.yml: replace build-deploy with publish job that pushes images
  to git.vicolab.de container registry
- docker-compose.prod.yml: pull-only compose for server deployments
  using registry images
